SPECIFICATION forming part of Letters Patent No. 656,978, dated August28, 1900.

Application filed January 5, 1900. Serial No. 495. (No model.)

To all whom it may concern:

Be it known that I, LINCOLN HOWARD, a citizen of the United States,residing at St. Joseph, in the county of Buchanan and State of Missouri,have invented certain new and useful Improvements in Heating-Stoves; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in combination coal and woodair-tight heatingstoves; and the objects of my improvements are, first,to provide an air tight stove equally suited to the consumption ofeither coal or wood; second, that will radiate a greater degree of headtoward the floor than other stoves; third, that will emit a largeramount of heat and consume a smaller amount of fuel than that emittedand consumed by other stoves, and, fourth, that will be more durablethan other sheet-iron heaters and have superior entrance and draftprovisions. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a longitudinal verticalsection of the stove, showing the construction of the interior. Fig. 2is a front View of the stove, and Fig. 3 is a vertical section of thesame on the line 3 3 of Fig. 1.

Similar letters refer to similar parts throughout the several views.

My invention consists of a drum A with a flat top and inverted conicalbase B, which tapers at an an le of about sixteen degrees. An opening inthe top covered by a hinged lid 0 affords access to the interior for supplying the stove with fuel.

The stove at its base or front is provided with an ash-pit entrance D,having upright sides (Z d and door (1, hinged at its bottom, by whichthe entrance to the ash-pit and stove is securely closed. Above the doorthere is a revoluble damper E, the base of which is cast as a part ofthe casting forming an entrance to the ash-pit. A grate F, supported bybrackets H H and set on a line horizontal with the top of the ash-pitentrance and divided through its center, adapts the stove to the use ofcoal. This grate not being attached to the stove may be easily liftedoff its brackets and taken out to permit the use of wood or for anypurpose.

The bottom of the stove is provided with a corrugated iron floor I,which fits in closely against the casing of the base on all sides andlies level with the bottom of the ash-pit door d, thus facilitating theremoval of the ashes. Inside the conical sides of the base there is acorrugated iron partition K of corresponding shape separated aboutthreefourths of an inch from the casing, its lower edge resting upon thecorrugated iron floor.

This partition is not rigidly attached to any part of the stove and maybe readily removed. Said corrugated partition is provided with a lateralflange L, formed by the top edge being bent outward. The ends of thecorrugations thus bent form ridges and valleys or furrows in thislateral flange, the ends of the furrows being adapted to reach acrossthe top of the narrow air-chamber and contact with the casing, while theridges, slightly reced-- ing, leave open spaces between, somewhat V-shaped, which serve as air-openings in the top of said air-chamber. Thispartition has perforations M M in the space above the ashpit door, thuspermitting draft connection between the revoluble damper immediately infront and the interior of the stove. The corrugations in the partitionextend vertically, and at the bottom of each alternate ridge of thecorrugations a piece about one and one-half inches high and two incheswide is cut out, leaving openings 0 O, that serve the dual purpose ofpermitting all soot and ashes that may sift in the space between thepartition and casing to readily drop through instead of lodging thereinandalso alford ing avenues for a part of the heat to be drawn into thespace between said partition and casing, said partition and base-casingthereby forming a heating-apartment inside the entire base-casing.

In the rear half of the stove there is a sheetiron diaphragmcheck-damper P, which is rigidly attached to the sides and rear of thedrum and is fitted closely thereto. On either side of the check-damperthere are two or more circular openings R R to enable any smoke that maycollect under the check-dam per and which may not be drawn forward andover the check-damper to readily pass up into the stove-pipe, which pipeis con'nect'edwith the stove-collar in the top of the drum directlyabove said check-damper. By means of this check-damper the heat thatwould largely escape from the stove through the pipe and chimney ischecked and spread within the stove, causing the stove to emit a greaterheat than it would otherwise give out.

The casing of the stove, including the drum base, top, and bottom, ispreferably constructed of sheet-iron and in oval form, the drum having ausual height of about ten inches and the conical base a height of aboutfourteen inches to secure the largest possible distribution of heat nearthe floor of the room; but the material, shape, and precise height maybe varied without departing from the essential features of my invention.

It will be seen that the chief object of this device is the constructionof a stove that will radiate the largest possible amount of heat towardthe floor of the building which is in closest proximity, but not beneaththe stove. This is accomplished, first, by means of the base of saidstove being of inverted conical form; second, by the partition inside ofsaid stove, which is of corresponding inverted conical form with saidbase and which partition while useful for protecting the sheet-iron inverted conical sides of the stove from being burned out by contact withthe fuel also constitutes one side of an inclosure for a heating chamberor compartment, into which a part of the products of combustion is drawnthrough the openings at the bottom of said partition andthe heat ofwhich products is radiated thence through said inverted conical sides ofthe stove toward the floor; third, by the check-damper, which by itsposition in the stove and peculiar construction is adapted tocheck theascent of the heat into the stovepipe, spread the heat, and drivedownward a large part of it into said heating-chamber between saidpartition and sheet-iron sides of the stove, out of which it will alsoradiate toward the floor, and, fourth, by the corrugated iron bottom inthe stove, the corrugations of which afford dead -air spaces between thesheet-iron casing underneath and said corrugated bottom, such spacesserving as regulators by preventing a too intense heat being radiateddirectly under the stove.

\Vhat 1 claim as my invention, and desire to secure by-Letters Patent,is-

1. A heating-stove comprising in combination an inverted frusto-conicalcombustionchamber, a partition or lining within said combustion-chamberand spaced therefrom to form a heating-chamber, said partition havingopenings at its top adjacent to the wall of the combustion-chamber andopenings at its bottom adjacent to the floor of the combustion-chamber,substantially as described.
